mf mw Vthat when the last group impulse is negative, the arm 96'L engages the arm 116, thereby prevnting the rotation of the shaft 1.16, necessary to the starting ot the si naling mechanism, and the transmitting mec anism will continue to operateuntil the last group impulse is negative. In the embodiment here illustrated three different signals which may be ,cairiagehift, the letter J and carriage release, are sent by the code wheel. It may b remarked, however, that the successive starting impulses of the code wheel are of different characteristics from those of the immediately preceding group impulses, the same as in the transmitting mechanism, and at the end of a given signal, the cam on the arm 123 drops off from the cam 104, on the wheel immediately below the cam on the arm 123, (Fig. 1) and sends a negative starting impulse, which starts the receiver. The extended notch in which the cam on the arm 123 is shown positioned in Fig. 1, permits the continued rotation of the code wheel 104, after the cam 5has dropped into its notch, and this permits the movement of the receiver to be arrested, be'- fore the transmitting mechanism begins operation.` The signal at the receiving station may be a single stroke of a bell which -is likewise produced at thetransmitting station by a mechanical arrangement, reference being had particularly to Figs. 3 and 7. The

bell is indicated at 125. A bell-crank 126 pivoted at 127 is provided with adjacent to the gear wheel 107. The other arm 126b is normally held against a stop 128 by a spring 129.v A lug 107a is secured on the face of the gear wheel 107 which engages the arm 126 from below and rocks the hell-crank, and when the lug 107* is disengaged from the arm 1263, the bell-crank isreturned to its normal position by spring 129 with suiicient force to cause the hammer 126 to engage the bell and give the operator an audible indication that the signalin member has com leted one revolution an that a correspon ingsignal has been given at the rec ivin station. The operator will hold the ande 114 in the position at the right, as viewed in Fig. 6, until the desired number of signals have been transmitted land when released, the rock shaft 116, to which 4the spring arm is secured, is returned to its ing atlits up er end a lateral projection 134, to which is attached the upper end of an over-centerin spring 135, the lower end of which 'is attac ied to stop arm 136, pivoted at its'upper end 137, so that, when the lower end of the arm is moved to the right, as viewed in Fig. 2, it comes in the path of movement of the arm 138, secured on the shaft of the transmitting mechanism, to stop the operation thereof between completed code combinations only and in position to maintain a receiver stop condition on the line. When the arm 131 is raised, by the slack being taken up in tlie'tape, the upper end of the arm 133 is moved to the right, which moves the spring 135 past the center of -tlie pivot 137 of the arm 136 and causes the lower end of the arm. to ysiiaplto the right into the path of movement' of the arm 138 on the shaft 70, and thereby stops the operation of the transmitting mechanism. When there is awain sufficient slack in the tape, the arm 131 drops and moves the rign 133 out of engagementwith the arm 3 In operation with the transmitter at rest, arm 138 will vengage stop arm, contact tongue 10 will remain in a position to continue the-line condition of the last selecting condition in the preceding code combination, and as disclosed in the copending application, the receiver will remain at rest. To start transmission, arm 131 is lowered either manually or by slacking of the tape due to perforation and stop 136 is removed from the path of arm 138 permitting shaft 7 0 to start into rotation. Lever 66f will first he actuated by its cam 69 and will permit lever 40f to operate under infiuence of its spring 41 to transmit a receiver start condition, the nature of which will be determined by theposition of extension 100. Thereafter, levers 66a to 66e permit arms 401 to 40e to move upward in succession and to position tongue 10 against contact 11 or 12 in accordance with the' 51. As'leve'r 66*7 moves upward projection 103 thereof shifts extension 100 out of the path member 101 and conditions arm 95 to be reset inacco'rdance with the movement of arm 40""to predetermine the nature of the perforationsin tape start impulse to be transmitted by 40t for the succeeding code combination.

In case the operator desires to transmit an auxiliary signal to another station, he moves operating handle 114 ofspring arm 113 to the right and holds it in this position until one of the notches 121a in disc 121 comes opposite roller 119, and until 96a is positioned out of the path of 116 when roller 119 will engage the notch 121a thereby freeing disc 122, thus stopping the movement of the signaling mechanism. The cams 104a on the code wheel 104 are formed to send through the levers 123, 66t and 40f, the conl" signaling means is at rest.
